To all whom it may concern:

Be it known that I, JONATHAN D. MAX- WELL, of Tarrytown, New York, have invented certain Im rovements in Coolers for Automobiles and t e Like, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings designating like parts.

This invention relates to automobiles and has for its object certain improvements by which I have secured a more perfect circulation of the cooling medium by a novel construction of the radiator and the siphon ducts leading thereto.

The various features of my invention will be illustrated and described fully in the accompanying drawings and specification and pointed out in the claims. y

In the drawings, Figure l illustrates in plan view the chassis of an automobile with the engine and cooler in view, parts being broken away for the sake of clearness Fig. 2 illustrates the same in side elevation, the sup orting frame being omitted for the sake of c earness Fig. 3 is a detached view of the radiator with parts of the front broken away to illustrate the internal construction of the radiator g Fig. 4 is a view in cross section taken on the central vertical line Fig. 3, and on an enlarged scale. Figs. 5 and 6 being views in side and front elevation respectively of the sleeve member through which the shaft starter traverses the radiator; and Fig. 7 a view in side elevation of the support for the starter.

In the embodiment of my invention selected for description and illustration as a convenient form to enable ready and complete understanding of my improvements, the part designated by the reference numeral l is the power shaft of an automobile su ported in a suitable frame comprising site members 2 and end members 3 of any convenient and suitable construction, the shaft being actuated by an engine 4, which in the instance illustrated takes the form of a wellknown type of explosion engine having cylinders 5 provided with jackets 6 from which lead Siphon ducts 7 conveying the heated water to the radiator 8, the construction of which will be described more at length hereinafter, and from which the cooled water Serial No. 280,451.

passes through ducts 9 back to the lower portions of the jackets.

In accordance with my invention I provide chambers 10, 11 and l2, into the first of which, 10 at the middle of the radiator, lead the hot water siphon ducts 7 to which reference has been made already, while the cold water ducts 9 lead from the bottom chamber 11, and the position of the mouths of these ducts is preferably about as illustrated in Fig. 3, i. e. the ducts 7 being removed a short distance from the sides of the radiator, while the mouths of the ducts 9 are about twice as far from the sides of the radiator. I prefer to apply these chambers to a radiator of the honey-comb ty e, and preferably to that particular form o' such radiator as I have illustrated, but to which form I do not limit myself, and the invention whereof I do not claim personally. One of the distinctive features of this type of radiator is found in the zig-Zag upri ht channels connected at every third bent with each other as illustrated at the portion of Fig. 3 broken away, this permitting an interchange of circulation in a direction transverse to the vertical aXis of the radiator, which I will designate for the sake of convenience a primary field.

In operation the hot water entering at 7 within the chamber 10 is able first to distribute itself somewhat through the chamber 10 before beginning to rise through the channels 13, and in so rising it follows a spreading course indicated by the arrows, being distributed completely over the upper field of the rear surface of the radiator until it reaches the chamber 12 by which time it is already fairly well cooled, and thereafter it descends through the portions of the channels at the front of the radiator, these being the coolest by reason of the forced suction produced by the fan from front to rear through the radiator, and by the time the water has rentered the mid-chamber 10, and has passed thence through the lower channels, which form what I designate for the sake of convenience a secondary held and reaches the bottom chamber l1, it is thoroughly cooled for withdrawal by the siphon ducts 9.

It will be observed that as the water is somewhat cooled before reaching the chamber l2, it is much less likely to lose in quantity by boiling, a common fault of radiators in which the water is allowed to reach the top without such predistribution as the chamber 10 insures, but I provide a steam chamber in the cap 14 and a vent pipe 15 extending down from the cap along the side of the radiator as indicated by dotted lines.

The reference numeral 16 designates a strainer for the supply of water which may be introduced upon removal of the cap 14.

In accordance with an important feature of my invention, I provide means whereby the crank shaft starter 17 shown in Figs. 1 and 2 may be inserted through the radiator to engage the shaft 1, thereby to make it unnecessary to place the radiator very high, or the shaft very low, or diminish the size of the radiator to avoid its traversal by the starter. For this purpose I utilize a sleeve 18, best seen in Figs. 5 and 6, having front-and rear flanges 19, presenting a periphery having integral bosses or notched projections 20 to receive the adjacent portions of the channel walls 13, which may be soldered or otherwise secured thereto.

To lend a strong support to the crankshaft starter I may ass through the sleeve 18 a bushing 21, inc ined slightly to be coaxial with the shaft 1, and provided with a web or foot 22 having screw or bolt holes 23 by which fastening means may be secured to the frame.

Having thus described my invention, what I claim and desire to secure by Letters Patent is z* 1. In an automobile, the combination with an engine having a cylinder with a jacket for cooling medium, of a radiator having upright channels forming a primary field and a secondary field for passage of the cooling medium, and a central chamber in communication with said channels and arranged substantially horizontally and medially across said radiator, to receive the heated fluid from said jacket, said fluid passing from said central chamber to said primary cooling field, whence it returns into said central chamber, and thence passes to said secondary cooling field, substantially as described.
